| I have been recently compiling up GNU emacs 18.55 and have run into a bit of a
| problem with the load-path variable.  The default load-path on our system is
| "/usr/local/emacs/lisp".  I would like to ADD to the list "/usr/local/lisp".
| 
| I tried setting it in "site-init.el" when compiling.  I used:
| 
| (setq load-path (append (list "/usr/local/lisp") load-path))
| 
| This had NO EFFECT.  When I fired up the new emacs and checked to see what my
| load-path was is only showed "/usr/local/emacs/lisp".  Putting the 'setq'
| statement into the default.el helps, but if someone needs that path for things
| in their ~/.emacs file, it causes an init file error (and rightfully so).  

I believe this is due to the way emacs dumps itself.

| Is there an easy way to insure that everyone has a particular load-path when
| starting up.  If they change it in their ".emacs", then that's their problem,
| but I would like to guarantee that they have the 2 mentioned paths in their
| load-path on startup.  

What I've done in the past is modify the PATH_LOADSEARCH define in
src/paths.h to have all of the directories you wish to seach,
separated by colons, ie:

	#define PATH_LOADSEARCH "/usr/local/emacs/lisp:/usr/local/lisp"

This works because src/lread.c has the following code:

	init_read ()
	{
	  char *normal = PATH_LOADSEARCH;
	  Lisp_Object normal_path;

	  /* Warn if dirs in the *standard* path don't exist.  */
	  normal_path = decode_env_path ("", normal);

decode_env_path breaks a PATH-type environment variable into a CONS
list....
